My fat sacs seem to get pretty slimey and gross inside of them. Its time to put them away for the winter. Any suggestions of how to clean them out and get them completely dry for winter storage? thanks!

I wouldn't put bleach in them as you might not get it all out and it could leak onto the carpet in the spring. Consider using a wet dry shop vac to get all the water out. I know there is a liquid additive you can buy at waterbed stores to keep the slime down.

Those are all good idea's. I think I will wash them out with a bleach water solution (very dilute), then rinse well with fresh water, then use the shop vac to suck all the extra water out, then hang them out to finish drying before storage. Thanks for the help!
